i HOT-WATER COOLER.

SPECIFICATION forming part of Letters Patent No. 756,061, dated March29, 1904.- Application filed July 31, 19031. Serial No. 167,61. (Nomodel.)

To all whom, it may concern,.-

Be it known that I, JAMES SIME Sco'r'r, a subject of the King of GreatBritain, .and a resident of. Brantford, in the Province of Ontario andDominion of Canada, have'invented a new and Improved Hot-Water Cooler,of which the fol-lowing is a full, clear, and exact description.

The object of the invention is to provide a new and improved hot-watercooler, more especially designed for use in connection with thewater-jacket of an explosive-engine or the like and arranged to insure aquick cooling of the water to keep the cylinder cool at an approximatelyuniform temperature.

The invention consists of novel features and parts and combinations ofthe same, as will be more fully described hereinafter and then pointedout in the claims. Y.

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure l is a side elevation of the improvement as applied. Fig. 2 is anenlarged sectional side elevation of the improvement; and Fig. 3 is aplan View of the same, parts being broken out.

The improved hot-water cooler A is preferably arranged in the upperportion of a water-tank B, connected at its lower end by a pipe C with apump D for forcing the Water through the water-jacket of the cylinder ofan engine E or other device, the said waterjacket having its outlet-pipeF connected with the cooler A, so lthat the hot water passing from thewater-jacket by way of the pipe F through the cooler A is cooled andcollected in the tank B for reuse. Y

The cooler A is provided with a casing G, having a transverse4 partitionG extending from the forward end of the casing to within a shortdistance of the rear end thereof, as plainly shown in Figs. 2 and 3, andfrom the vrear end of this partition G extends forwardly and upwardly aperforated plate H, leadingto the bottom I of an inlet-chamber J,

` into which the hot water is discharged by the Apipe F. The end of thebottom vI adjacent tov the perforated plate H is curved upwardly, as atI, and a downwardly-curved plate I2 is secured to the top of the casingG and extends into the water-inlet chamber J, as plainly shown in Fig.2, so that the said curved portions .I and I2 form a trap to dissoAcharge the water from the inlet-chamber J into a mixing-chamber K,formed in the casing G between the top thereof andthe perf` rated plateH. The perforated plate H also forms, with the partition G', anair-inlet chamber L, connected at its outer end by apipe N withablowerNof any approved construction,

so that air under pressure .is forced through the pipe N into theair-chamber L, from which the air passes through the perforations in theplate H to mix with the water flowing into the chamber vK by way of thetrap between the chambers K and J.

The water and air from the chamber K flow around the curved outer end G3of the casing G into a chamber P, arranged above the bottom G2 of thecasing G, the top of the chamber P being formed by a perforated plate O,

which extends from the inner end of the par' tition G to the bottom G2near the outer end thereof, as plainly indicated in Fig. 2. Theperforated plate O forms, with the partition G', a water-dischargechamber Q, having an outlet Q for discharging the cooled water andv theair back into the tank B.

The water and air flowing around the end G3 of the casing and throughthe perforations in the plate O are divided or sprayed, so that bymixing the water with the air in the chamber K and spraying the waterand the air into the discharge-chamber Q the water is thoroughly cooledand passes in this condition,

with the air, through the outlet Q into the tank in which the wateraccumulates, while the air readily escapjes from the upper open end ofthe tank.

The device is very simple and durable in construction and can be readilyapplied to insure a rapid cooling of the hot water, so as to allow reuseof the water for cooling purposes in the water-jacket of anexplosive-engine or other machine on which the device is used.

A suitable purging compound may be placed in the water in the tank B, soas to prevent the formation of scales in the water-jacket of the engine.

Having thus described my invention, Iclaim as new and desire to secureby Letters Patentl. A hot-water cooler comprising a mixingchamber, awater-supply chamber connected with the hot-water supply and providedwith a trap discharging the water into the said mixing-chamber, anair-supply chamber connected with an air-supply and located below andseparated from the said mixing-chamber by a perforated partition, and asprayingchamber connected with the mixing-chamber and having aperforated top plate for dividing or spraying the water and air, as setforth.

2. A hot-water cooler comprising a mixingchamber, a water-supply chamberconnected with the hot-water supply and provided with a trap dischargingthe water into the said mixing-chamber, an air-supply chamber connectedwith an air-supply and located below and separated from the saidmixing-chamber by a perforated partition, a spraying-chamber connectedwith the mixing-chamber and having a perforated top plate for dividingor spraying the water and air, and an outletchamber, into which passesthe sprayed air and water, the outlet having a discharge, as set forth.

3. A hot-water cooler comprising a casing having a transverse partitionextending from theouter end of the casing to within a short distance ofthe inner end thereof, perforated plates on opposite sides of the saidpartition, extending from the inner end thereof outwardly, the one toform a mixing-chamber and an air-chamber and the other to form aspraying-chamber, a discharge-chamber within the said casing, and awaterinlet chamber connected with a water-supply, for discharging thewater into the said mixing-chamber, as set forth.

4. A hot-water cooler comprising a casing having a transverse partitionextending from the outer end of the casing to within a short distance ofthe inner end thereof, perforated plates on opposite sides of the saidpartition, extending from the inner end thereof outwardly, the one toform a mixing-chamber and an air-chamber and the other to form aspraying-chamber, a discharge-chamber within the said casing, awater-inlet chamber 4connected with a water-supply, for discharging thewater into the said mixing-chamber, and a trap between the saidwater-inlet chamber and the mixing-chamber, the trap being formed byplates, curved in opposite directions and spaced apart, as set forth.

5. In a hot-water cooler, a casinginclosing a mixing-chamber, anair-inlet chamber, a spraying-chamber, and an outlet-chamber, thespraying-chamber being an extension of the mixing-chamber, themixing-chamber being separated from the air-inlet chamber by a erforatedpartition and the spraying-chamber being separated from theoutlet-chamber by a similar partition, means for simultaneously forcinga current of air and water together into said mixing-chamber to mix thetwo together, and thence when mixed, forcing the same on through theintervening perforated wall into the spraying-chamber, and an outlet forsaid spraying-chamber.

6. In a hot-water cooler, a casing inclosing a mixing-chamber, awater-inlet chamber leading into said mixingchamber, a sprayingchamberforming a continuation of said mixing-chamber, an air-inlet chamberleading into the mixing-chamber between said water-inlet chamber andsaid spraying-chamber, means for forcing the water into saidmixing-charnber and thence into said spraying-chamber, means for forcingair into the mixing-chamber simultaneously with the water to mix the twoand thence, when thus mixed, through said spraying-chamber onward intosaid outletchamber, and an outlet for said last-named chamber.

7. A hot-water cooler comprising a casing having a transverse partitionextending from the outer end of the casing to within a short distance ofthe inner end thereof, perforated plates on opposite sides of the saidpartition, the upper one of which plates extends outwardly and upwardly,and the lower one of which extends outwardly and downwardly, the upperplate forming, with the casing, a mixing-chamber at its top side, andforming with the central plate an air-inlet chamber at its under side,the lower one of said plates forming, with the casing, aspraying-chamber at its under side, and with the central plate, anoutletchamber at its upper side.
